A Novel Approach to Support Majority Voting in Spatial Group McDm Using Density Induced Owa Operator for Seismic Vulnerability Assessment

Abstract

ABSTRACT:Being one of the most frightening disasters, earthquakes frequently cause huge damages to buildings, facilities and human beings. Although the prediction of characteristics of an earthquake seems to be impossible, its loss and damage is predictable in advance. Seismic loss estimation models tend to evaluate the extent to which the urban areas are vulnerable to earthquakes. Many factors contribute to the vulnerability of urban areas against earthquakes including age and height of buildings, the quality of the materials, the density of population and the location of flammable facilities. Therefore, seismic vulnerability assessment is a multi-criteria problem. A number of multi criteria decision making models have been proposed based on a single expert. The main objective of this paper is to propose a model which facilitates group multi criteria decision making based on the concept of majority voting. The main idea of majority voting is providing a computational tool to measure the degree to which different experts support each other's opinions and make a decision regarding this measure. The applicability of this model is examined in Tehran metropolitan area which is located in a seismically active region. The results indicate that neglecting the experts which get lower degrees of support from others enables the decision makers to avoid the extreme strategies. Moreover, a computational method is proposed to calculate the degree of optimism in the experts' opinions.

Urban vulnerability assessment: Advances from the strategic planning outlook

“…Kimani-Murage et al ( 2014) went a step further by putting forth a more extensive survey in order to assess how the affected inhabitants defined, perceived and experienced crisis. Another qualitative step forward was taken by Moradi et al (2014) when assessing the degree of subjectivity in expert judgement, and its possible influence on the decision-making process. The latter is an important issue due to the fact that taking into account the participatory process is a necessary, but not p. 19 of 46 a sufficient condition (Munda, 2004), and thus some kind of weighting should be provided to allow for aggregation of the results provided by participatory processes.…”

Non-Parametric Wavelet Functional Analysis for Horizontal and Vertical displacements Derived from GPS Stations in Western Alaska during the Year 2012

“…At Akutan volcano the deformation was essentially related to the intrusion of a large dike in 1996 and to its after effects (Lu et al 2000c) as well as the volcanic deformation retrieved in Westdahl volcano, at the western end of Unimak Island (Lu et al 2000b;Mann and Freymueller 2003). Moreover, the complex seismicity pattern requires accurate methods in order to infer both horizontal (the combination of North-South and East-West directions) and vertical (upward/downward direction) displacements during coseismic periods (Moradi et al 2014;Moradi et al 2015;Khamespanah et al 2016).…”

Earthquake Vulnerability Assessment for Hospital Buildings Using a Gis-Based Group Multi Criteria Decision Making Approach: A Case Study of Tehran, Iran

“…Tehran is situated in a seismically active region in Middle East and it is dramatically threatened by earthquake (M Moradi, Delavar, Moshiri, & Khamespanah, 2014). In recent years, Tehran became a centre for many financial, educational and recreational activities.…”
